Police have locked down a block of flats after reports of a wanted man barricaded inside the building.
The man is believed to be speaking to his lawyer on the phone.
It is understood that the 25-year-old man is wanted by police in relation to theft, deception and assault-related offences in the Fitzroy and Collingwood areas.
Nearby streets have been shut down and police have surrounded the building, as well as the Critical Incident Response team.
Police arrived at the scene at approximately 5am to arrest the man, on Waterdale Road in the Heidelberg Heights area, but he has not come out of his house.
The man is believed to be on his own, but it is feared that he may be armed.
Nearby residents have been told to stay inside and lock their doors.
